Duct unit

Abstract

This item is a duct unit comprising a standpipe, a pipe joint, a eaves gutter, and a cover. The standpipe is arranged along the wall of the building, the eaves gutter is arranged along the roof of the building, and the top of the eaves gutter is covered with a cover. A slit-shaped opening is provided between the eaves gutter and the cover, facing the roof. The top of the standpipe is connected to the eaves gutter, and the bottom of the standpipe is connected to the pipe joint. The pipe joint consists of a main pipe and three branch pipes that protrude from the outer wall of the main pipe, and the branch pipes may protrude either upward or downward. As shown in the reference diagram showing the usage status, a connecting pipe to the underground pipe is connected to the bottom of the pipe fitting, wiring is passed through the upper and lower branch pipes to install snow melting heaters inside the vertical pipe and connecting pipe, wiring is passed through the middle branch pipe to install a temperature sensor inside the vertical pipe, and the temperature inside the vertical pipe is monitored from the outside while controlling the temperature of the snow melting heater, so that warm air generated by geothermal heat inside the underground pipe can be guided into the vertical pipe and blown onto the roof of the building through the slit between the eaves gutter and the cover, melting the snow on the roof.
